Martin Skrtel is attracting interest from at least two Turkish clubs, including champions Besiktas, with his future at Liverpool all but over this summer.

The long-serving centre-back was restricted to just 27 appearances in all competitions throughout 2015-16, starting just four games since the turn of the year.

In particular, his display against Southampton marked the start of the end for Skrtel's Liverpool career. At St Mary's, he replaced Dejan Lovren at half-time with the Reds leading 2-0, only for the Saints to come from behind and win 3-2, profitting from a number of avoidable errors which Skrtel was culpable for.

Defender's eight-and-a-half-year Anfield spell over

As a result of his downturn in form, the 31-year-old's time on Merseyside now seems to be up. Despite having been at the club since 2008, the defender finds himself behind at least the rejuvenated Lovren, Mamadou Sakho and incoming centre-back Joel Matip, who joins from Schalke on a free transfer, in the pecking order.

But there is plenty of interest in Skrtel's services, with title-winners Besiktas - who knocked Liverpool out of the Europa League in 2014-15 - interested and even recently-promoted side Middlesbrough having been linked.

The Slovakian, who will captain his country's national team at UEFA Euro 2016 this summer and will take on several of his English and Welsh teammates in Group B, is currently considering his options.

A loyal servant to the club since moving to Anfield from Zenit St Petersburg, Skrtel has made a total of 320 appearances and was awarded Liverpool's Player of the Year in 2012.

He is one of the few remaining players from the Reds' last silverware-winning side as they beat Cardiff City on penalties to win the League Cup in 2012, the defender netting an equaliser on the hour mark to force extra-time.

However, he sat out the final of the same competition this season and also remained on the substitutes' bench for the Reds' 3-1 Europa League final defeat at the hands of Sevilla.

Despite a disappointing last two years, Skrtel is sure to leave with the best wishes of the club's supporters. He turned down Manchester City in 2012 as well as rejecting the advances of Inter Milan in July 2015, shortly before penning a new three-year deal at the club.

Skrtel appeared to bid an emotional farewell in front of the Liverpool away supporters on the final day of the season against West Bromwich Albion, his manager comforting him with a hug. 

Reds hoping to strengthen in several key areas over the summer

Sentimentality aside, Jürgen Klopp remains keen to recruit in a number of positions, having already signed Matip, Marko Grujić and goalkeeper Loris Karius for a combined total of less than £10 million.

Amongst his targets is thought to be young Leicester City left-back Ben Chilwell, with Alberto Moreno's inconsistent performances having frustrated across the past 12 months.

Borussia Monchengladbach midfielder Mahmoud Dahoud is also high up on the list of priorities as Klopp looks to reconstruct the Reds' side in the centre of the park.

With any move for Mario Gotze now appearing unlikely, the playmaker unwilling to leave Bayern Munich despite seemingly having little part to play in Bavaria, the Reds could turn their attentions to Southampton forward Sadio Mane - who has long been a player Klopp has been impressed by.

The Liverpool Echo have however dismissed reports that Aston Villa left-back Jordan Amavi, currently recovering from a serious knee injury, could be a target.
